3 TEST REPORT Rendered to: AFCO INDUSTRIES, INC Roy Street Alexandria, Louisiana Report No.: A Test Date: 12/15/10 Report Date: 01/03/ General Information 1.1 Product Redi-Rail 1.2 Type Aluminum Guardrail System 1.3 Project Description Architectural Testing was contracted by AFCO Industries, Inc. to conduct structural performance tests on the 96 in wide by 42 in high Redi-Rail l aluminum level guardrail system. The system was evaluated for the design load requirements of the following building codes: 2009 International Building Code, International Code Council 2009 International Residential Code, International Code Council Structural tests were performed according to Chapter 17 (Structural Tests and Special Inspections) of IBC Limitations All tests performed were to evaluate structural performance of the guardrail assembly to carry and transfer imposed loads to the supporting structure. The test specimens evaluated included the infill, rails and rail brackets. The posts are not a tested component and are included in the test setup only to facilitate the rail bracket anchorage. 130 Derry Court York, PA phone: fax:

The specimens were loaded using an electric winch mounted to a rigid steel test frame. High strength steel cables, nylon straps, and load distribution beams were used to impose test loads on the specimens. Applied load was measured using an electronic load cell located in-line with the loading system. Electronic linear motion transducers were used to measure deflections.

5 A Page 3 of Test Setup The 96 in wide by 42 in high level guardrail assembly was installed and tested as a single railing section by directly securing the aluminum posts into a rigid steel test fixture, which rigidly restrained the posts from deflecting. The posts are not a tested component and are included in the test setup only to facilitate the rail bracket anchorage. Transducers mounted to an independent reference frame were located to record movement of reference points on the guardrail system components (ends and mid-point) to determine net component deflections. See photographs in Appendix B for individual test setups. 2.3 Test Procedure Each test specimen was inspected prior to testing to verify size and general condition of the materials, assembly, and installation. No potentially compromising defects were observed prior to testing. An initial load, not exceeding 50% of design load, was applied and transducers were zeroed. Load was then applied at a steady uniform rate until reaching 2.0 times design load in no less than 10 seconds. After reaching 2.0 times design load, the load was released. After allowing a minimum period of one minute for stabilization, load was reapplied to the initial load level used at the start of the loading procedure, and deflections were recorded and used to analyze recovery. Load was then increased at a steady uniform rate until reaching 2.5 times design load or until failure occurred. The testing time was continually recorded from the application of initial test load until the ultimate test load was reached. 2.4 Test Results The following tests were performed on the level guardrail assemblies for the design load requirements of the codes referenced. Deflection and permanent set were component deflections relative to their end-points; they were not overall system displacements. All loads and displacement measurements were horizontal, unless noted otherwise. Key to Test Results Tables: Load Level: Target test load Test Load: Actual applied load at the designated load level (target). Where more than one value is reported, the test load was the range (min.-max.) that was held during the time indicated in the test. Elapsed Time (E.T.): The amount of time into the test with zero established at the beginning of the loading procedure. Where more than one value is reported, the time was the range (start-end) that the designated load level was reached and sustained.
